s390/qeth: handle sysfs error during initialization
[ Upstream commit 9111e7880ccf419548c7b0887df020b08eadb075 ]
When setting up the device from within the layer discipline's
probe routine, creating the layer-specific sysfs attributes can fail.
Report this error back to the caller, and handle it by
releasing the layer discipline.
